I already knew that I was using my fingers to make a small hole to see things, and if the light was bright enough, I could see clearly, but the light was too dark and I couldn't see clearly. In fact, it is the same to squint and see things clearly.
That's because through the orifices, the light entering the human eye is concentrated in the center of the cornea, which is much smaller than the pupil, so that the difference is reduced. Because the human cornea and lens are not standard spherical (aspherical), the closer to the center the refractive power is, when the light is limited to a very small range, the effect of farsightedness, myopia and astigmatism is very insignificant, and when the myopia is low, this method can improve vision, but it is not to correct myopia. Because this is also effective for farsightedness and astigmatism, but it reduces the impact of farsightedness and astigmatism on vision.
It is just said that 200-degree myopia can only be seen in the normal pupil size, but can be seen after passing through the small hole; A normal pupil of 400 degrees only sees the possible value through the aperture), and the orifice continues to shrink, and the visual acuity will be further improved. However, the smaller the aperture, the less light will enter the eye, and if the light is too dim, it will still not be able to see clearly. If the prescription is too high, the hole needs to be narrowed to a small size to achieve adequate vision, but if the light is insufficient, it is difficult to have the best of both worlds.
It is medically believed that within a certain range, miosis can improve vision, while dilated pupils can reduce vision. It's a truth. As a result, dilated pupils can cause blurred vision.

-How can it be. I tried how I couldn't see clearly.

It's normal for young people to lack self-control, like you love to play with the computer and watch TV, these are common hobbies to many people your age, the key is to understand the consequences of indulging in these things!!
If you want to take the military academy, the physical requirements are the first, playing on the computer and watching TV for a long time will definitely damage your eyesight, lead to vision loss, cause myopia and a series of problems, you have to take into account, this will directly affect your future! In addition, military schools should also have excellent academic performance, play computers and watch TV for a long time, and leave their studies aside, which will have an impact on their future is self-evident!
If you want to ** a habit, then replace it with other things, you can arrange sufficient learning tasks for yourself, so that you have no time for entertainment, you can also make a fixed exercise plan, instead of playing on the computer and watching TV, or let parents strictly control the contact time of network TV, in short, there must be an effective limiting force to control yourself, you can't control yourself, just use the power of your parents!

I don't know a lot about eye hospitals, but I still know about the more famous ones, such as Shanghai-New Vision Ophthalmology-Hospital, their technology and experts are very good, and they can still be trusted!

Whether it is true myopia or false myopia, it will develop in depth!
So pay attention to eye hygiene!
The best way to do this is to learn a set of ways to restore your eyesight!
Let's talk about the causes of myopia first: if you continue to look at near objects for a long time, it will cause ciliary muscle spasm, which will lead to increased force counting. For example, the current computer family in the operation of the computer, look at the file, input text, look up at the screen and other repetitive actions, eye activity is extremely frequent, these actions have to rely on the eye muscle - the control of the ciliary muscle, if the teenager long-term close to the eyes to read and write or do not pay attention to eye hygiene, over time will cause the ciliary muscle to be in a state of tension will not relax so that the adjustment function declines, the lens can not work normally, resulting in myopia in adolescents.
So overcome the above bad eye habits!
Since the ciliary muscles are overly tense, there is a way to relax them, which means that myopia is reversible, and this can be done with appropriate methods. In this way, the ciliary muscles are trained to retract and release freely, and the lens returns to normal work, thus restoring vision. The training is also very simple, the initial time may take one to two hours (because you have to learn the method, only a few minutes a day is enough) after a week of training will have obvious results, if you can stick to a few minutes a day, the eye vision will get better and better!
This method of restoring myopia without medicine, surgery, instrumentation, and no effect is feasible, and I used this method to restore my vision!
True myopia is "irreversible", "cannot" and "mirror-only" gradually penetrated into the hearts of the people, and it has become a conclusive conclusion!
Finally, may you have good eyes!

1): Apply cycloplegic agents (atropine, double star, tropicamide eye drops, Bausch & Lomb eye drops, etc.) to dilate the pupils, and spot the eyes once before bedtime. (2):
Stick to eye exercises, 3 to 4 times a day. (3): After studying or working for 1 2 hours, overlook the natural scenery and rest for 10 to 15 minutes to relax the ciliary muscles.
4): Use traditional Chinese medicine acupuncture, electroacupuncture, qigong or hot massage to improve the excitability of the visual nerve center; Acupuncture recommends acupuncture "eye" and "post-ball" acupuncture. (5):
Reading and writing should be kept at a distance of more than 30 cm from the written and correct posture; Don't tilt your head to read, the light should be suitable for the eyes; It is necessary to combine work and rest, and pay attention to exercise.

When you reach adulthood, you can have surgery to solve the myopia problem.

The myopia rate in China is close to 30%, primary school students suffer from myopia, the myopia rate in junior high school has soared to high school students wearing glasses, and the myopia rate of college students is as high as 80%.
There are many causes of myopia, according to our guess, the factors that cause myopia are: genetic factors, environmental factors, individual factors, nutritional factors and sleep factors. The main causes of myopia in primary school students are doing homework too late, lack of sleep, excessive TV and computer play, and intake of a lot of German protein.
There is now a high rate of myopia among elementary school students. Although there are some genetic factors for myopia, it is more important to influence external factors. At present, there is no more effective way to do it than wear glasses, but to carry out preventive measures in a lasting way.
Although there is a certain relationship between the extremely high myopia rate of middle school students and the current education system, it is more due to eye habits that lead to the occurrence of myopia. The focus of myopia prevention is also to develop good eye habits.

Problem analysis: This is normal, the average degree is relatively stable in adulthood, but in the past 5 years, it is normal for you to grow more than 100 degrees.
Suggestions: Myopia patients wear appropriate glasses, pay attention to eye hygiene, do not guess brief eye fatigue, do more eye exercises, myopia will stabilize at a certain level. Therefore, after you are myopia, you need to regularly go to the ophthalmology department of the hospital to check the prescription, and if you find that the prescription increases, you need to replace the lenses in time, otherwise the prescription of the glasses will increase faster.
Theoretically it is infinite, but in practice, folding 7 times in half is already the maximum, and I have tried, even if it is very thin paper, it can be folded in half up to 7 times!!
People who work as clerks are too hard, dealing with all kinds of paper every day, and there are always injuries on their hands with a lot of small cuts, and then it doesn't hurt too much and it's not very serious for a few days, but it's too disturbing. The legendary mosquito does not bite people, but responds to people. >>>More
12 times. Theoretically, if the thickness of the paper is zero, it can be folded in half countless times, however, due to the existence of the actual thickness of the paper, this theory does not exist, because the width of the folded paper cannot be less than or equal to the thickness of the paper, that is to say, the width of the paper after folding should be greater than 1mm for a piece of paper with a thickness of 1mm. >>>More
